Yes, the hose can delaminate internally and act like a one-way valve.

One way to check is to jack up the axle in question, apply & release the 
brakes and while noting the drag, crack open the bleed screw. If a little 
bit of brake fluid is expelled and the drag is noticeably reduced then a 
faulty hose is likely.
